Badly Designed Roundabouts?

arescarti42 18 March 2009 36

I was just wondering if anyone else has noticed or has issues with a few roundabouts in Canberra that seem badly designed. The main one that comes to mind for me is the big one on the intersection of Coranderrk Street and Parkes Way near the city. My issue with it is that coming from the southeast on Parkes Way and turning right onto Coranderrk, both lanes have right turn markings on them. This means that when you are turning right from the left lane, there is the potential to be cutting in front of people who are coming from Coranderrk St. and about to travel north west on Parkes Way. This of course happens when you’re slowing down to take the corner, and they’re speeding up to exit the roundabout.

Though I can’t put my finger on any other specific ones, I seem to remember roundabouts around the city where you are forced to change lanes within them or are otherwise not well laid out.

Does anyone else find this?

Or am I just too picky?

Top of Anzac Parade – going north, turning onto Limestone. Where most of the traffic here turns left

Well, many very important drivers decide that they are to good to wait in the left lanes to turn left so they enter the roundabout in the right lane, do a complete 360 around the roundabout and force the less important drivers to give way to them as they exit. This is the type of self centred driving style that is so common in Canberra. I’m sure that speed cameras will eventually fix the problem though!!!!

Hate to burst your bubble buddy but this is not an illegal act and in no way does it interfere with the northbound drivers turning left onto Limestone Avenue. Observe that the so called “important drivers” are forced into the inside lane of the roundabout when completing a 360 maneuvre thus on their westbound exit onto Limestone Avenue, they are in no way hindering the northbound traffic from Anzac Pde. Rather, the issue is the timid drivers who are unware they can still legally turn left whilst the outside lane is clear, even if the inside lane is not.

We all just have to live with the fact that we are privy to drivers who just have NFI re roundabouts.

I am no better driver than any other but I do take note of road rules to ensure I do not hinder fellow drivers. Also, rather than being part of the ‘flock’, I will continue to complete a 360 maneuvre which actually aids the traffic problem at the very north end of Anzaz Pde of an evening. I am only one less car sitting there, idling away belching out emissions! Tree huggers should love me.

Fair point about the fact that you can technically still turn left at that roundabout while people do a 360 turn (actually more like 405 degree turn), although i wouldn’t call the people who give way to both lanes “timid” drivers. I’ve seen enough drivers change lanes whilst in a roundabout (to my knowledge illegal) to know that assuming the person in the right lane isn’t going to change lanes is a risky maneuver.

If they hit you when you’re turning left, is it you who is at fault for not giving way to all vehicles on the roundabout (like the road rules say), or their fault for changing lanes? (I believe it is illegal to change lanes in any intersection).

Yep – I don’t do it, but I’m always happy when someone else does – it gives the looooong line of left turners a chance to go.

That roundabout works fine if you imagine the inner ring being a straight road with five consecutive roundabouts (all with one road to the right).

Gasp! I wonder how difficult that would be to negotiate if you were driving a semi trailer or one of those articulated buses?

There is a bus here, (http://maps.google.com/maps?ie=UTF8&ll=51.562865,-1.771371&spn=0.000859,0.002843&t=h&z=19) it seems to be doing fine because the roundabout is pretty big, but the instructional signage apparently starts quite a while back for what you’re meant to be doing.

http://en.wikipedia.org/wiki/File:Swindon_Magic_Roundabout_eng.svg Gasp! I wonder how difficult that would be to negotiate if you were driving a semi trailer or one of those articulated buses? I wonder why they didn’t just put in a normal roundabout, maybe to distribute traffic better or something?

In Swindon UK there is a large roundabout with 5 or 6 smaller roundabouts attached to it, its known as ‘the magic roundabout’.

You guys think CBR round–bouts are scary I suggest you never drive in the UK. On the large ones there often found on motorway exits and 5 or 6 way intersections not only do you HAVE to change lanes within the roundabout they also have bloody traffic lights too. Not just on the approaches like a couple in Sydney but on the roundaout itself.

Most of ours are pretty logical if you use half a brain whilst driving.

Thank you JC! I’ve never driven in the UK but I must admit I am a little bemused at the confusion. If people think that there may be potential for a collision due to lane markings, I would suggest that they brush up on their give way rules. It all seems pretty simple to me.

There’s no problem with that roundabout, the problem lies with the people using it. It’s not uncommon to be able to make a right turn from the left lane at a roundabout with only 3 sides (when properly marked), the cars turning right from parkes way should be giving way to the vehicles in either lane, they’re just as likely to be taken out by the turning right from the right lane if they don’t.

I use the one you mentioned every day…it’s never been an issue.

Indeed. I do that turn every single day as well. You just apply commonsense and consideration. If you’re coming in from Parkes Way and there’s a car coming around from the right and heading into Parkes Way, you slow down and let it go ahead before you turn right into Corranderrk. If you have time, you cut across and keep out of the way. Visibility very clear from all directions. No excuses for not negotiating it successfully!

Aaaw I’ve never seen it, but that might be because I’m negotiating it near peak time when I need to watch the road carefully when negotiating that roundabout, the barriers block out short cars for me.

The new set of lights at the end of the flyover, near the BBP entrance, will be online on the 25th as that’s when the work on that strech of road finishes, kinda sorta, according to the airport management. They’ll still do things but at night, they say.

If you drive into Canberra from Queanbeyan via past the airport, the first roundabout you hit after the new crossover bridge has the following graffiti sprayed on the concrete walls in the middle.

“No more traffic lights you dumb bums.”

Now that’s a far more passionate way to make a statement then doing so online! Crude but effective.

Heh, i saw that one too. I let out a silent cheer the first time I drove by it.

Saw someone this afternoon who failed to give way to a vehicle exiting from the right hand lane of the big roundie north of Woden Town Centre. Fortunately the exiting driver was awake and nothing more than an application of the brakes was required.

Aargh!! Where is the edit. Its Canberra Ave and Wentworth Ave where I almost had the head on.

hark40 hark40 7:04 pm 18 Mar 09

Roundabouts!! Gotta love them. The big one at Kingston on Canberra Ave/Williams Dr wsas one I almost had a head on crash. No idea how that lady was going the wrong way on that roundabout.

What about the one on Gundaroo Dr at Crace? The ability to merge after exiting that roundabout is an accident waiting to happen once traffic levels increase when Crace is developed.

The one on Parkes Way is an interesting design and potentially confusing. I just take it easy and look, look and look and look again regardless of which lane I am in while turning right into Civic.

One area where traffic lights has helped is at the Moorsehead Dr/Monaro Hwy/Pialigo Rd intersection. Flow through that intersection is better than it has been, but that could also be due to the extra lanes. Just don’t talk to me about the idiots that turn right from Monaro onto Pialigo and sit in the middle of the intersection of a morning. Those coming from Fairbairn Ave (Moorsehead) heading south don’t get a chance to get through when they get the few seconds of green lights.

arescarti42 – I think you’re correct, the roundabout is badly designed. Traffic coming from the (South-)East direction should not be instructed to turn right from the left lane.

However, traffic coming from the North are OK to turn right from the left lane because it is only a 3-way roundabout – the “South” entrance to it is missing… think of the right turn from the North entrance as replacing a “South exit.”

Personally, I don’t see too many drivers having issue with the roundabout, but still agree it should be different.

In that situation, since the truck is already in the roundabout, the car has to give way to it. (Yes, you need to look out not just for traffic to the right of you as you enter the roundabout, but traffic “ahead” of you already in the roundabout).
